Abstract: Details are given of a numerical and experimental study into buckling of steel ellipsoidal domes loaded by static external pressure. A range of geometries and thicknesses of domes is examined, ...

Abstract: The plenum-aerated biofilter (PA biofilter) is an unsaturated, single pass vertical flow biofilter with horizontal air plena within the media to enhance passive aeration. Plena enlarge the surface area of the air/media ...

Abstract: A methodology was developed to monitor and evaluate the removal of solids and associated constituents by a nutrient separating baffle box (NSBB) storm-water treatment device treating runoff from a 4.3 ha (10.6 acre) ...

Abstract: Passive biological filtration for nitrate removal from storm-water drainage is challenged by highly transient mass loadings, the need to adequately supply an electron donor, and potential inhibition by dissolved oxygen ...

Abstract: The statistical trends of the duration of extreme wave conditions, as characterized by hindcast wave information, are investigated at five sites along the coast of the United States. Identification of extreme events and ...

Abstract: The cost‐effective optimization of rubble‐mound breakwater cross sections requires a summation of all the life cycle costs for each alternative design, including construction costs, maintenance costs and associated economic ...

Abstract: This paper concerns the time optimal control of a system variable where the controlling input is bounded, as is usually the case, and the system is subject to arbitrary disturbances. An ...

Abstract: Fifteen groups composed of engineering students and professionals were videotaped while performing a simulated design task. Using interaction analysis, it was found that professional teams were ...
